APPARATUS FOR ABSORBING GASES.

SPECIFICATION forming part of Letters Patent No. 395,(391, dated January 8, 1889.

Application filed December 17, 1887\ Serial No. 258,1G5. (No norlel.)

To all whom it may conccrn:

Be it known that I, FREDERICK CARLIsLE, a

citizen ot' the United States, residing at Frank lin, Essex county, New Jersey, have invented certain new and useful Improvements in Apparatus for the Absorptiof of Gases, fully described and represented in the following specification and the aecompanying drawings, t'orning a part of the same.

Io My invention consists in an improved construction for exposing an absorhing-fluid to the action of a The Construction consists in a series of sloping con'ductors provided each with a receptacle at one end, the receptacle being open at one side, and thereby adapted to overflow at the end ot' the conductor to discharge the fluid upon its under side, the fluid dripping t'ron the lower end of each conductor ot' the 2o series into the receptacle of the succeeding conductor, and thus being distributed in turn over the under sides of all the conductors.

It also consists in a inanit'old arrangeinent of the series of comluctors by which the eas 2 5 is forced to rise sinultaneously through a series ot' parallel inclined spaces, where it is brought into the most iutin'n'te contact with the gases.

These constructions are shown in the annexed drawing-s, in which Figure 1 a plan, partly in section online w' x' in Fig. 2, ot' a casing for several series of conductors with an attached vaporizing-furnace and gas-channel.

3 5 section of the same on line in Fig. l. Fig. is a transverse section on line y in Fig. 5 of part of the casing and one of the conductors upon a much larger scale; Fig. 4, a transverse section of a conductor ot' alternative 40 Construction; Fig. 5, a longitudinal section ot' the receptacle upon the upper end of the conductor upon a larger scale than Fig. 1.

In Fig's 1 and 2, A is the casing inclosing a chamber, A', containing' a series of conductors, b b' I) Zr Zr* Zf. These 'conductors are each slightly inclined to promote the flow of the fluid along its under surface, and are provided each with a small receptacle or dripcup, c, at its upper end, the receptacles of the upper series being supplied with the absorbing-fiuid by pipes d froni a tank, d'.

Fig. 2 is a vertical,

Each receptacle is open at the upper end ot the conductor and incloses the fluid upon all other sides, so that the liquid which accumulates therein runs over the end of the 5 5 conductor, which is preferably concave, as at e in Fig. 1, to direct the fluid to its middle. The ,fluid adheres to the under side of the. conductor, as it is often seen to do upon the under side'of sloping root-heams when the roof leaks, and may te directed from the lower end ot' the conductor into a similar receptacle by a lip, f. The fluid is thus transferred froni one series of conductors to the other, running' along their under surfaces throughout its entire course, and finally dripping from the lower ends of the last series into a suitable tank or receptacle, E, from which it may be drawn by a cock, F.

At G is shown a furnace containing a sulphur-pot, 72 and a nitenpot, 1', to generate the fumes used in the production of sulphuric acid. From the furnace the gas is shown conducted through a bent passage, J, and nozzle J" into the lower part of the chanber A', a 75 A steau-jet being shown at k to facilitate the discharge ot' thegases thereto.

A pipe, m, is shown conducted from the upper part ot' the chamher to the passage J adjoining the furnace, and a stean-pipe, 72, So shown connected therewith to induce a current of the gases which have been uncombined with the .fluid in the chamber, that they may be returned again to the lower part ot' the chanber through the nozzle r 8 5 The apparatus for generating and supplying the gas to the chanber forms no part of ny present invention; but it will be seen that when introduced therein it is :forced by the rna'it'old arrangemenfiot' the several se- 9 ries of inclined conductors to flow simultaneously into the series ot' parallel spaces 0 between the several conductors, its upper passage being obstructed in all other directions by' the approximatiou of the conductors to the walls of the chainber upon every side. The eases therefore pass between and beneath the several conductors, and when they reach the upper ends of the lower series flow naturally into the spaces of the series above, I and are thus kept in the closest contact With the fluid exposed upon their under surfaces.

' the casing A.

In addition to the grooves or anglesp, formed at the edges of the conductors, longitudinal grooves may be formed intermediateto those at the sides, as shown in Fig. 4, by which means the liquid may be prevented from running to one edge of the conductor when supplied to its under surface, the intermediate grooves, p', confining the liquid to the several tongues which exists between them upon the conductor.

The conductors are in practice inclined about one and one-half inch to each foot, which produces a suitable velocity in the current.

I am aware that heretofore perforated plates have been superposed upon one another and connected by hydraulic lutes around their edges, the openings being flanged to prevent the discharge of the liquid through the opening until it had accumulated to a certain depth upon the upper surface of the plate, and the lower surfaces of the plates being inclined to diffuse the fluid upon the same. therefore claim, broadly, the mere exposure of the fluid upon the under surface of a conductor, but have devised a constri'ction which may be cheaply made of wood and lead, and adapted to bring the gas into the closest possible contact with the under sul-faces ot' the conductors, as I have shown in the parallel spaces 0 in Fig. 2 of my drawings. ,By the Construction shown in Figs. 3 and 4 I also prevent the liquid from flowing from the conductors upon the sides of the chanber in which they are retained, and by the provision of the receptacle c at the upper ends of the conductors and the arrangement of the manifold series of conductors, with their lower ends over a series of such receptacles, I am enabled to greatly increase the surface of the conductors within a chamber of given capacity, while the gas is forced to divide into thin films to pass 'from the lower part of the chamber upward through the narrow spaces o.

The is necessarily introduced at the I do not bottom of the chamber, as it is desirable to have it move in the opposite direction from the current of absorbing-fluid, which, by its gravity, necessarily flows downward from the point where it is supplied.

I am aware of the state of the art in United States Patents Nos. ?05,974, 309,968, 180,901, and 284317, and wholly disclain the constructions shown therein.

What I claim and desire to secure is- 1. In an apparatus for absorbing gases by a liquid, the combination, with the narrow chamber A', of a series of longitudinal inclined conductors arranged one above another and provided each with'a receptacle upon its upper end, the receptacle being open upon one side toward .the higher end of the conductor, and thereby adapted to discharge the V fluid over theend of the conductor upon its a liquid, the combination, with the narrow.

chanber A', of a series of longitudinal inclined con'd uctors arranged on e above another and provided 'each with a receptacle upon its upper end, the receptacle being open upon one. side toward thehigher end of the conductor, and thereby adapted to discharge the fluid over the end of the conductor upon its under side, and the conductor being grooved or bent adjacent to the casing of the chamber A', to confine the fluid to the under side of the conductor, as and for the purpose set forth.

3. In an apparatus for absorbing gases by a liquid, the conbination, with the narrow chamber A', of several series of sloping conductors arranged one above the other, with the narrow spaces 0 between the several conductors, each conductor being .provided with a receptacle at its upper end, such receptacle being open upon one side toward the higher end of the con d uctor to discharge the fluid over the end of the conductor upon its under side, and the lower ends of the conductors being arran ged over the receptacles of the conductors beneath the same, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribng witnesses.- v
